STATES FATENT @FEF GENERATOR.

To all whom it may concern 1 Be it known that I, DAVID C, DUNoAN, a citizen of the United States, residing at Duluth, in the county of St. Louis and State of Minnesota, have invented certain new and useful Improvements in Generators, of which the following is a specification, reference be ing had thereinto the accompanying drawing.

This invention relates to acetylene gas generators and has special reference to that type known as low pressure portable generators comprising an upright water tank or container in which the necessary water for generating is carried, said container being open in the upper end thereof, and a vertically removable bell or gas tank, supporting internally thereof the cage or holder for the carbide. or carbic cakes as the briquetted carbide is commonly called.

Such generators are moved about from place to place by hand, or on vehicles, and are used in many classes of work; during the moving of which it is found that the vibration or motion will cause the water in the container to splash or surge out of the upper open end thereof, which is obviously objectionable in many respects.

To overcome this slushing out of the water in the container is the principal object of my present invention, while other objects and advantages of the peculiar construction will appear in the further description thereof.

Referring to the accompanying drawing forming part of this application and in which like'reference characters indicate like parts: I

Figure 1 1s a central vertical section of an acetylene gas generator showing in elevation my anti-slushing device or baflle installed therein; while Figure 2 is an enlarged top plan view of the improved baflle.

1 represents the cylindrical sheet metal water tank or container which is open at the top and has suspended therein the gas-bell 2, said bell being suspended upon the cross arm 3 ordinarily held in position upon the container by means of suitable wing nuts and hinged bolts 4 and 5 respectively. 6

represents the cylindrical back pressure valve which is installed adjacent the body portion of the gas bell 2 and ordinarily extends into the water in the container.

My improved baflie head is installed about Application filed August 9, 1923.

sure valve, preferably some little distance below the upper end of the container 1, within or adjacent the normal water level, and comprises two spaced heads 7 and 8 of metal or wood. These heads are permanently spaced apart by suitable radially disposed division walls 9 and are permanently attached to the heads 7 and 8. The double head thus formed is divided into two equal parts with the upper edges thereof turned down forming lugs 10, as it were, which are unitable by small bolts 11. The baffle has an axial hole 12 therein for the reception of the body of the gas bell, and also a hole 13 therein into which the back pressure valve fits, so that the head may be separated before being placed about the gas bell and pressure valve, then. drawn up tightly to fit same. An auxiliary cover 14 is provided for the hole 13, the halves of said cover being fastened to the upper face of the uppermost head of the baffle by suitable screw bolts 15 which are mounted in slotted holes in the baffle so that they may be readilyadjusted to more tightly fit the back pessure valve.

The battle is made slightly smaller in diameter than the inside .diameter of the con tainer and the close fitting of same about the gas bell and pressure valve is somewhat immaterial, though must be sufficiently so as to prevent a large volume of water passing same, and, in fact, either or both baflle heads may be perforated if desired.

In practice such adevice has proven exceedingly efficient, the annoyance of splashing out of the water out of the container in any considerable quantity being entirely doneaway with, as during the surging 0f the container it is found that the water cannot objectionably splash out above the uppermost head of the baffle, as but little motion of water intermediate of the heads and the division walls can possibly take place, thus adequately insuring against sloshing over of the water in the container and yet does not prevent free discharge of the water from the container in the event of the latter being accidentally upset, the advantages of which are well known to those versed in the art.

Having thus described my invention, what I claim and desire to secure by Letters Patcut, is: V

1. The combination with a gas generator comprising an upright cylindrical water container, a gas bell suspended ithin said container, and an upright back pressure Valve adjacent the gas bell, of a horizontally disposed anti -slushing battle surrounding said gas bell and back pressure valve, said battle being separable diametrically of the gas bell and back pressure valve for convenient adjustment thereabouts.

2. The combination with a gas generator comprising an upright cylindrical Water container, a gas bell suspended Within said container, and an upright bacl: pressure Valve adjacent the gas bell, of a horizontally disposed anti -slushing battle surrounding said gas bell and back pressure valve, said battle being separable diametrically, and independently adjustable encircling means carried' b the battle surrounding the back pressure valve.

8. In an acetylene generator an anti-slushing battle comprising two concentrically mounted spaced heads having axial openings theretlnzough and radially disposed division walls intermediate of the heads acting as spacing means therefor and dividing said space into a plurality of compartments for the purpose described.
